Improve successful economic battery monitoring program

Support the infrastructure of modern society must be based on a very high reliability of operation. Internet and telecommunications switching center server farms in order to ensure nearly 100% of the "trouble-free run-time" or system availability, they mostly rely on a very mature technology - lead-acid batteries, while the data storage center are used in high-tech. Typically, these key nodes, and many other important sectors are equipped with standby power, standby power supply is generally the first level inverter Sony PCGA-BP2NX Sony VGP-BPS2 sony VGP-BPS8, inverter pairs of VRLA (VRLA) battery or a similar performance, sealed gel batteries assembled battery Section of power conversion. The reason why the traditional techniques widely used, there are many reasons, especially lead-acid batteries affordable, but also with outstanding reliability. But while great but not perfect. VRLA battery life is limited (generally 12 years design life), often mission-critical systems using this battery as a backup power supply Apple iBook Blueberry Series Apple iBook FireWire Series, but changed regularly.

Failure may indeed occur to apple a1036 adapter. In a typical standby power systems, the role of the battery as its name - they always maintain a fully charged state of waiting for the main power failure. And the fully charged state of continuous small current through the "float" charge to maintain. If the float current is below a set limit, then the battery inside the gases produced by electrolysis will be re-chemical combination. In this case, a single battery float voltage is even slightly higher than the standard value of 2.27 V, may also damage the battery VGP-BPS9 VGP-BPS9A/B Sony VGP-BPS3. Slightly over-voltage will cause precipitation of the electrolyte capacity of more than Recombination more gas, these gases are not handled through the overflow valve. If the battery temperature is too high, even if the charging voltage is appropriate, can lead to electrolyte loss.

Other failure modes include early sulfation, very bad columns and grid connection, grid connection plate and the bad, electrolyte stratification and grid accelerate corrosion. There is yet another, though a small but catastrophic failure modes - thermal runaway, which is peculiar to VRLA gel batteries such as Toshiba Satellite P100 battery Toshiba Satellite P105 battery, and a failure modes, can lead to burst into flames. The only way to prevent thermal runaway is to monitor the internal temperature of the battery.

Just monitoring the battery voltage on the detection of lead-acid battery capacity decline in the role is very limited, it has been recognized throughout the industry. When the battery performance is declining, it is usually presented is that the nominal voltage, until the release of large currents can only apparent, but when its capacity has been severely reduced voltage drop prematurely. By measuring the proportion of electrolyte to determine the exact battery status, the method of the VRLA or sealed gel batteries does not apply; routine, the test battery VGP-BPS9/S 319411-001 Pavilion dv2000 Battery used in the only way is to discharge the battery pack to a controlled state of the following Pavilion dv6000 Battery HSTNN-LB31, but this approach need to stop using the battery. In addition, the depth of discharge also reduces the life of lead-acid battery; in on a regular basis to conduct its backup battery discharge test, as well as its main power supply with high reliability of the system, most programs use this test to determine battery life.

Recently, continuous monitoring can be of non-intervention electronic method can detect a single cell near the failure state, this method can not only save costs, while maintaining overall system availability. The predecessor of such systems is usually measured cell or battery pack or 45Wh Apple PowerBook G4 Adapter or 65Wh Apple PowerBook G4 Adapter (battery industry term which means that within the shell in the same package multiple battery) voltage - despite its limitations is well known - with charge / discharge current and ambient temperature. Some systems attempt to measure or guess the battery internal resistance, its effectiveness varies.

LEM's Sentinel system is dependent on the basic parameters of a simple analog measurements of change leading product has now grown to the first three generation of the Sentinel III. It is custom-designed single-chip SoC (System on Chip) IC on the integration of analog and digital technology PA3399U-1BRS Acer Aspire 3000 battery BTP-58A1. The device configured in a measured terminal voltage, the battery internal temperature and internal resistance of the module, can provide accurate measurement results for the cost again in most of the backup system configuration can afford within the budget of the system, it is the design of a key elements.

The main performance indicators of rechargeable batteries

Safety performance indicators for battery failure is unacceptable. In which the greatest impact is the explosion and leakage. The occurrence of explosions and leakage mainly related to the battery internal pressure, structure and process design (such as valve failure to Acer LCBTP03003 Latitude D600 Battery Latitude D610 Battery, there is no lithium-ion battery protection circuit, etc.) and should be prohibited by the incorrect operation (for example, a battery into a fire) of the. To AA 2300mAh Ni-MH rechargeable batteries, for example, indicates that the batteries 230mA (0.1C) charge 16 hours after 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of electricity for the 2300mAh. Accordingly, if 230mA of current discharge, the discharge time is about 10 hours with 45Wh Apple PowerBook G4 Adapter.

 

Refers to a certain discharge conditions, the battery can release the total electricity consumption. In accordance with IEC standard and GB, nickel cadmium and nickel-metal hydride batteries in 20 ± 5 ° C conditions, in order to 0.1C to 0.2C charge 16 hours after discharge to the 1.0V power emitted when the Dell Latitude D620 Battery Dell Inspiron 710m Battery Dell Latitude D800 Battery's rated capacity to C expression; Lithium-ion battery at room temperature, constant current (1C), constant-voltage (4.2V) after 3 hours under the condition of charge to 0.2C discharge to 2.75V emitted when the battery's rated capacity of electricity. The unit of mAh battery capacity, and Ah (1Ah = 1000mAh).

Battery internal resistance refers to the current flowing through the Sony VGP-BPS12 battery when the subject of internal resistance. Charging the battery internal resistance is small between ibook g4 adapter and APple A1021 adapter, need to use special equipment can only be measured more accurate results. Generally known as the battery internal resistance is the charge-state resistance, meaning that the battery is fully charged when the resistance (corresponding to a discharge state of resistance, saying that after the battery fully discharge resistance by 65Wh Apple PowerBook G4 Adapter. Generally speaking, the discharge state of resistance Charge-state resistance than the large, and not very stable). The greater the battery internal resistance, the battery itself consumes energy more efficient use of the battery lower.

A great resistance when the battery charge is very severe fever to Sony PCGA-BP2NY battery PCGA-BP51 battery, so that the battery temperature is rising sharply. The impact on the battery and charger are all great. With the increase in the number of battery life, due to the consumption of electrolyte and battery internal chemical activity in the reduction of internal resistance of the battery will have different degrees of increase. The worse the quality of the battery up faster. Cycle life batteries that can be experienced repeated charge and discharge cycles to Dell Inspiron 510m Battery VGP-BPS9/B Sony VGP-BPS5. Battery life and capacity into the inverse relationship, the general Ni-MH battery cycle life of up to 500 times or more. High-capacity battery life is shorter, although up to 200 times or more. With the charge-discharge cycle life is also closely related to the conditions, generally the greater the charge current (faster charging), the shorter the cycle life.

Charge retention ability that is often talked about self-discharge, that means open-circuit state, the battery storage of electricity in certain environmental conditions to maintain the ability. Mainly by self-discharge battery materials, manufacturing processes, storage conditions, and many other factors with Sony VGP-BPS2  VGP-BPS9/S Dell Inspiron 1721 Battery. That the large current discharge capability. Digital cameras, power tools, electric toys, electric appliances in particular need to have excellent large current discharge performance of the battery. Large current discharge performance of primary and battery-related materials and production processes.

Usually the higher the temperature the greater the self-discharge rate. Rechargeable battery to a certain extent of self-discharge is normal to apple a1036 adapter or 45Wh Apple PowerBook G4 Adapter. With nickel-metal hydride batteries, for example, IEC standards require that the battery is fully charged after the temperature of 20 ± 5 ° C, humidity 65 ± 20% conditions, the open set aside 28 days, 0.2C discharge time of not less than 3 hours (ie, residual consumption is greater than 60%). Lithium-ion batteries and dry battery self-discharge is much smaller than Dell Latitude D620 Battery.
